Apache POI 是创建和维护操作各种符合Office Open XML(OOXML)标准和微软的OLE 2复合文档格式(OLE2)的Java API。用它可以使用Java读取和创建,修改MS Excel文件.而且,还可以使用Java读取和创建MS Word和MSPowerPoint文件。Apache POI 提供Java操作Excel解决方案(适用于Excel97-2008)。
简单理解就是通过POI,java可以与office建立联系。
本次项目实践基于SSM框架,简单封装了Excel批量导入导出功能,实现过程如下
1. maven导入java包:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.5-FINAL</version>
</dependency>
2. 建立Excel实体--ExcelBean
/**

public class ExcelBean implements java.io.Serializable {
private String headTextName;//列头(标题)名
private String propertyName;//对应字段名
private Integer cols;//合并单元格数
private XSSFCellStyle cellStyle;
public ExcelBean(){
}
public ExcelBean(String headTextName, String propertyName){
this.headTextName = headTextName;
this.propertyName = propertyName;
}
public ExcelBean(String headTextName, String propertyName, Integer cols) {
super();
this.headTextName = headTextName;
this.propertyName = propertyName;
this.cols = cols;
}
public String getHeadTextName() {
return headTextName;
}
public void setHeadTextName(String headTextName) {
this.headTextName = headTextName;
}
public String getPropertyName() {
return propertyName;
}
public void setPropertyName(String propertyName) {
this.propertyName = propertyName;
}
public Integer getCols() {
return cols;
}
public void setCols(Integer cols) {
this.cols = cols;
}
public XSSFCellStyle getCellStyle() {
return cellStyle;
}
public void setCellStyle(XSSFCellStyle cellStyle) {
this.cellStyle = cellStyle;
}
}
3. 封装Excel工具类--ExcelUtils
4. 在HTML页面导入需要的js
<script type="text/javascript" src="${ctxPath}/js/jquery-form.js"></script>
5. 在HTML添加测试控件
<form id="uploadForm" enctype="multipart/form-data" method="post">
<input id="upfile" type="file" name="upfile">
<input type="button" value="导入" id="upLoadPayerCreditInfoExcel" name="btn">
</form>
<a href="${ctxPath}/creditInfo/downLoadReceverCreditInfoExcel.html">导出</a>
6. 导出通过a标签的get请求即可以实现,导入则通过ajax的post请求实现:
$('#upLoadPayerCreditInfoExcel').click(function(){
var cacheVersion=$("#cacheVersion").val();
if(checkData()){
$('#uploadForm').ajaxSubmit({
url:$("#root").val()+'/creditInfo/uploadReceiverCreditInfoExcel.html',
data:{'cacheVersion':cacheVersion},
dataType: 'text'
});
}
});
//JS校验form表单信息
function checkData(){
var fileDir = $("#upfile").val();
var suffix = fileDir.substr(fileDir.lastIndexOf("."));
if("" == fileDir){
alert("选择需要导入的Excel文件!");
return false;
}
if(".xls" != suffix && ".xlsx" != suffix ){
alert("选择Excel格式的文件导入!");
return false;
}
return true;
}
7. controller端实现
导出:
@RequestMapping(value = "/downLoadPayerCreditInfoExcel", method = RequestMethod.GET)
@ResponseBody
public void downLoadPayerCreditInfoExcel(HttpServletRequest request,HttpServletResponse response,HttpSession session){
response.reset();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmssms");
String dateStr = sdf.format(new Date());
Long companyId=UserUtils.getCompanyIdBySession(session);
Map<String,Object> map=new HashMap<String,Object>();
// 指定下载的文件名
response.setHeader("Content-Disposition", "attachment;filename=" +dateStr+".xlsx");
response.setContentType("application/vnd.ms-excel;charset=UTF-8");
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
XSSFWorkbook workbook=null;
try {
//导出Excel对象
workbook = creditInfoService.exportPayerCreditInfoExcel(companyId);
} catch (IllegalArgumentException | IllegalAccessException
| InvocationTargetException | ClassNotFoundException
| IntrospectionException | ParseException e1) {
e1.printStackTrace();
}
OutputStream output;
try {
output = response.getOutputStream();
BufferedOutputStream bufferedOutPut = new BufferedOutputStream(output);
bufferedOutPut.flush();
workbook.write(bufferedOutPut);
bufferedOutPut.close();
} catch (IOException e) {
e.printStackTrace();
}
}
导入:
@ResponseBody
@RequestMapping(value="uploadPayerCreditInfoExcel",method={RequestMethod.GET,RequestMethod.POST})
Public void uploadPayerCreditInfoExcel(HttpServletRequest request,HttpServletResponse response,HttpSession session) throws Exception {
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile file = multipartRequest.getFile("upfile");
if(file.isEmpty()){
throw new Exception("文件不存在!");
}
Long companyId=UserUtils.getCompanyIdBySession(session);
Long userId=UserUtils.getUserIdBySession(session);
InputStream in = file.getInputStream();
creditInfoService.uploadPayerCreditInfoExcel(in,file,companyId,userId);
in.close();
PrintWriter out = null;
response.setCharacterEncoding("utf-8"); //防止ajax接受到的中文信息乱码
out = response.getWriter();
out.print("文件导入成功!");
out.flush();
out.close();
}
8、service层
导入,从excel中获得数据放入List<List<object>>中,然后遍历放入实体,执行插入操作:
public void uploadPayerCreditInfoExcel(InputStream in, MultipartFile file,Long companyId,Long userId) throws Exception {
List<List<Object>> listob = ExcelUtils.getBankListByExcel(in,file.getOriginalFilename());
List<CreditInfoBean> creditInfoList=new ArrayList<CreditInfoBean>();
for (int i = 0; i < listob.size(); i++) {
List<Object> ob = listob.get(i);
CreditInfoBean creditInfoBean = new CreditInfoBean();
creditInfoBean.setCompanyName(String.valueOf(ob.get(0)));
creditInfoBean.setBillType(String.valueOf(ob.get(1)));
creditInfoBean.setBillNumber(String.valueOf(ob.get(2)));
BigDecimal bd=new BigDecimal(String.valueOf(ob.get(3)));
creditInfoBean.setBuyerBillAmount(bd.setScale(2, BigDecimal.ROUND_HALF_UP));
creditInfoBean.setReceiveTime(String.valueOf(ob.get(4)));
creditInfoBean.setBuyerRemark(String.valueOf(ob.get(5)));
creditInfoList.add(creditInfoBean);
}
}
导出:
public XSSFWorkbook exportPayerCreditInfoExcel(Long companyId) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException, ClassNotFoundException, IntrospectionException, com.sun.tools.example.debug.expr.ParseException {
List<CreditInfoBean> creditInfoList=creditInfoDao.listAllPayerCreditInfoPage(companyId);
List<ExcelBean> ems=new ArrayList<>();
Map<Integer,List<ExcelBean>>map=new LinkedHashMap<>();
XSSFWorkbook book=null;
ems.add(new ExcelBean("供应商名称","companyName",0));
ems.add(new ExcelBean("票据类型","billType",0));
ems.add(new ExcelBean("票据号","billNumber",0));
// ems.add(new ExcelBean("买方是否参与","isBuyerIquidation",0));
ems.add(new ExcelBean("票据金额","buyerBillAmount",0));
ems.add(new ExcelBean("应付日期","buyerPayTime",0));
ems.add(new ExcelBean("剩余天数","overplusDays",0));
ems.add(new ExcelBean("状态","buyerBillStatus",0));
map.put(0, ems);
List<CreditInfoBean> afterChangeList=changeBuyerStatus(creditInfoList);
book=ExcelUtils.createExcelFile(CreditInfoBean.class, afterChangeList, map, "应付账款信息");
return book;
}
